IoT-based Sensor System for Stop Line Traffic Area Using ATmega2560 Microcontroller

Internet of Things (IoT) based sensor systems has provided sophisticated services by connecting objects based on information exchange technology. This paper proposes the development of an IoT-based sensor system for monitoring stop line traffic area using the Atmega2560 microcontroller. The focus on traffic monitoring was chosen because currently traffic enforcement is one of the efforts to reduce the number of accidents and increase progress in the traffic system. The sensor used is an ultrasonic sensor connected to the SIM800L module. The ultrasonic sensor will work when the driver or motorist crosses the line by sending text message to the device, while the camera in the sensor system will monitor and capture images of violation in the traffic area. The sensor will not work if the reading distance above 110mm, since the distance indicates that the traffic line is heading in the opposite direction.
